[asterisk-speech-rec] Help With Lumenvox

[Stephen Keller]

So what does your /etc/asterisk/lumenvox.conf file look like? Try adjusting the volume and SNR sensitivity settings down.

If you wait 15 seconds -- the SpeechBackground timeout -- does it ever return?

No  , only timeout if i set the timeout replacing
exten => s,3,SpeechBackground(GP-DeliveryorTakeout)

to

exten => s,3,SpeechBackground(GP-DeliveryorTakeout|15)

Does the lumenvox-asterisk test, the [lumenvox-test] dialplan in the help file, exhibit exactly the same behavior?

Yes
Does it ever return?

No return. Wait infinitelly on the first execution


One thing that can cause problems is if you speak IMMEDIATELY as soon as the prompt in SpeechBackground starts playing.

No i will wait 1-3 seconds to start speak and no result
You need to give the Speech Engine about 250-500 ms to initialize some background noise detection stuff before you can barge in. This is almost never a problem in production (callers generally listen to the prompt at least that long) but in testing overzealous developers who know the prompt have a tendency to do this.
